文中采用解析方法,运用弹道导弹红外辐射模型和卫星探测能力计算模型,建立了SBIRSHEO对潜地弹道导弹的覆盖范围和探测能力模型,并对SBIRSHEO-4的覆盖能力进行仿真计算,通过与STK软件中模型的仿真结果对比验证,证明了所建模型符合实际情况。考虑卫星观测角与大气透过率对SBIRSHEO探测能力的影响,并做进一步仿真分析,此时结果更贴近于SBIRSHEO卫星的实际探测能力。

Using ballistic missile infrared radiation model and satellite detectability calculation model, established the scope and detect-ability model of the SBIRS HEO to submarine-launched ballistic missile (SLBM) by analytic method in this paper, and the coverage ability of HEO-4 was simulated and calculated. Comparing with the results of the model in software STK, it was proved that the model conformed to the the actual situation. Considering the influence of satellite observation angle and atmospheric transmittance on SBIRS HEO detection ability, further simulation and analysis were carried out, and the results were more close to the actual detection ability of satellite SBIRS HEO.
